quick commercial bid question

I'm sending in my first commercial bid shortly, it's for an apartment complex (Didn't realize how much luck you can have just calling around to apartment buildings and stuff). Anyways, it's 2 acres with substantial trimming around fences, parking lots, etc. . . the gates are all wide enought to get my mower through, but the sections with grass are very broken up. . . like nine seperate areas with grass. I'm thinking about bidding in the $200 (Canadian) per cut range. It's in sort of a low income region. Do you think I'm high/low or what? Thanks in advance for the help.

'bout half way between Windsor and London. . . I know $200 is normally pretty high for 2 acres, but I'm figuring that this is easily a 4-5 hour job. There's just too many areas that are impractical for the z-turn and will have to be cut with the 21"
